Android - generating random possition near me with markers

Hi there I want to implement this code into my but don't knew how to set it to work

I got problem with return statement and than how to create mark with the random genarate possition Can you please tell me how to get working the method getrandomLocation in creating Markers?

  public Location getRandomLocation() {
        Location location = new Location("");
        LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
    int radius = 10;


                   double x0 = latLng.latitude;
            double y0 = latLng.longitude;

            Random random = new Random();

            // Convert radius from meters to degrees
            double radiusInDegrees = radius / 111000f;

            double u = random.nextDouble();
            double v = random.nextDouble();
            double w = radiusInDegrees * Math.sqrt(u);
            double t = 2 * Math.PI * v;
            double x = w * Math.cos(t);
            double y = w * Math.sin(t);

            // Adjust the x-coordinate for the shrinking of the east-west distances
            double new_x = x / Math.cos(y0);

            double foundLatitude = new_x + x0;
            double foundLongitude = y + y0;
            LatLng randomLatLng = new LatLng(foundLatitude, foundLongitude);

            Location loc = new Location("");
            loc.setLatitude(randomLatLng.latitude);
            loc.setLongitude(randomLatLng.longitude);

//dont know what to return
        return ;
    }

    public final void addMarker(GoogleMap mMap) {
//dont know how to get working the getRandomLocation())
        mMap.addMarker( new MarkerOptions()
              //  .position(new LatLng(48.349723, 18.052405))
                .position(getRandomLocation())
                .title("krokodíl")
                .icon(BitmapDescriptorFactory.fromBitmap(resizeMapIcons("krokodil", 100, 100))));

        mMap.addMarker(new MarkerOptions()
               // .position(new LatLng(48.310025, 18.038878))
                .position(getRandomLocation())
                .icon(BitmapDescriptorFactory.fromBitmap(resizeMapIcons("fretka", 100, 100)))
                .title("fretk"));
        mMap.addMarker (new MarkerOptions()
                .title("hroch")
                .icon(BitmapDescriptorFactory.fromBitmap(resizeMapIcons("hroch", 100, 100)))
                //  .title()
                //.snippet(mObj.getNumber(Configs.MONSTERS_MONSTER_POINTS) + " points")
               // .position(new LatLng(48.318569, 18.055767)));
                 .position(getRandomLocation()));
    }
